Autometer gauges are ordered- good advice appreciated

I finally bit the bullet and ordered my new autometer gauges from Summit. They are all Sport Comp and electrical gauges, except the speedometer which is mechanical. I also ordered the Lokar 80" speedo cable, which is a little too long, but it was the closest I could find.
Couple of questions I still need answered:

Are the speedometer cable ports on the 727, A833, and 904 transmissions the same? The Lokar cable I ordered fits the 727 for sure, but I have an A833.

Also, can that cable be wrapped behind the dash in a sweeping path, or should I cut it and resolder/weld it back together to fit the car? I don't don't want to get it jammed and ruin the gear in the tranny.

Also, any tips or pointers you all have would be greatly appreciated. Thanks.
